Product Description
This test chamber is suitable for high and low temperature tests and rapid temperature change tests of finished products and components, so as to evaluate the performance and quality of the test samples. It has the following several basic characteristics:
1.The structure design of the test system is advanced and reasonable, the manufacturing process is standardized, the appearance is beautiful and elegant, and the maintenance is convenient.
2. The matching and assembly of components are well-matched. The main functional components all adopt original imported parts with international advanced levels, which enhances the safety and reliability of the product and can meet the users' requirements for long-term and high-frequency use.
3. The necessary conditions for the normal operation of the equipment have been provided. The buyer only needs to offer power and electricity, test consumables (such as distilled water or purified water), and a working environment that meets the requirements.
